Pimple is also called as the Zit, acne vulgaris or spot. The main
cause of the pimples is blockage of the skin pores on the face. The
sebaceous gland produces the sebum. The excessive production comes out
from the skin pores. But at the teenage and puberty the skin becomes
thick. The thickness of the skin and clogging of the skin pores with the
dead skin cells leads to the pimples on the face.
